Abstract
BACKGROUND Posterior spinal instrumentation and fusion (PSIF) for adolescent idiopathic scoliosis (AIS) can be lengthy and complication-ridden. The aim of this study was to evaluate the effect of surgical time on perioperative complications in this procedure when controlling for confounding variables with propensity score analysis. METHODS This was an IRB-approved review of electronic health records from 2010 to 2019 at a single tertiary care children's hospital. Patients undergoing PSIF were grouped into "short" (< 6 h) or "long" (≥ 6 h) surgical time groups. Outcome measures were estimated blood loss (EBL), cell saver transfusions, packed red blood cell (pRBC) transfusions, length of stay (LOS), intraoperative monitoring (IOM) alerts, hematocrit, ICU transfer, neurologic loss, surgical site infection, and 90-day readmissions. We controlled for age, sex, BMI, curve severity, number of segments fused, and surgeon factors. RESULTS After propensity score matching there were 113 patients in each group. The short surgical time group had lower EBL (median 715, IQR 550-900 vs median 875, IQR 650-1100 cc; p < 0.001), received less cell saver blood (median 120, IQR 60-168 vs median 160, IQR 97-225 cc; p = 0.001), received less intraoperative pRBCs (median 0, IQR 0-0 vs median 0, IQR 0-320, p = 0.002), had shorter average LOS (4.8 ± 1.7 vs 5.4 ± 2.5 days; p = 0.039), and fewer IOM alerts (4.3% vs 18%, p = 0.003). CONCLUSIONS Patients with shorter surgical times had less blood loss, received less transfused blood, had a shorter LOS, and fewer IOM alerts compared to patients with longer surgical times. Surgical times < 6 h may have safety and efficacy advantages over longer times. LEVEL OF EVIDENCE III.

Abstract
PURPOSE The aim of this study was to characterize antibiotic prophylaxis practices in pediatric patients who have received posterior arthrodesis for spinal deformity and understand how these practices impact 30-day postoperative infection rates. METHODS This was a retrospective cohort study using the National Surgical Quality Improvement Program Pediatric database for year 2021. Patients 18 years of age or younger who received posterior arthrodesis for scoliosis or kyphosis correction were included. The outcome of interest was 30-day postoperative infection. Fisher's exact test and multivariable regression analysis were used to analyze the impact of intravenous antibiotic prophylaxis, intraoperative intravenous antibiotic redosing after 4 h, postoperative antibiotic prophylaxis, intraoperative topical antibiotics on 30-day postoperative infection, and various antibiotic prophylaxis regimens. RESULTS A total of 6974 patients were included in this study. The 30-day infection rate was 2.9%. Presurgical intravenous antibiotic (11.5% vs. 2.7%, p = 0.005), postoperative antibiotic (5.7% vs. 2.4%, p < 0.01), and intraoperative topical antibiotic (4.0% vs. 2.7%, p = 0.019) were associated with significantly reduced infection rates. There was no significant difference in infection rates between patients that received cefazolin versus vancomycin versus clindamycin. The addition of Gram-negative coverage did not result in significant differences in infection rates. Multivariable regression analysis found postoperative intravenous antibiotics and intraoperative topical antibiotics to reduce infection rates. CONCLUSIONS We found the use of presurgical intravenous antibiotics, postoperative intravenous antibiotics, and intraoperative topical antibiotics to significantly reduce infection rates. Results from this study can be applied to future research on implementation of standardized infection prevention protocols. LEVEL OF EVIDENCE Level II.

Abstract
Current best practice guidelines recommend a plastics-style multilayer wound closure for high-risk pediatric spine surgery. However, plastic surgery closure of spinal incisions remains controversial. This study investigates surgeon perceptions and practice patterns regarding plastic surgery multilayered closure (PMC) in pediatric spine surgery. All surgeons in an international pediatric spine study group received a 30-question survey assessing incisional closure practices, frequency of plastic surgery collaboration, and drain management. Relationship to practice size, setting, geographic region, and individual diagnoses were analyzed. 87/178 (49%) surgeons responded from 79% of participating sites. Plastics utilization rates differed by diagnosis: neuromuscular scoliosis 16.9%, early onset scoliosis 7.8%, adolescent idiopathic scoliosis 2.8% (P < 0.0001). Plastics were used more for early onset scoliosis [odds ratio (OR) 18.5, 95% confidence interval (CI): 8.5, 40.2; P < 0.001] and neuromuscular scoliosis [OR 29.2 (12.2, 69.9); P < 0.001] than adolescent idiopathic scoliosis. Plastics use was unrelated to practice size, setting, or geographic region (P ≥ 0.09). Respondents used plastics more often for spina bifida and underweight patients compared to all other indications (P < 0.001). Compared to orthopaedic management, drains were utilized more often by plastic surgery (85 vs. 21%, P = 0.06) and for longer durations (P = 0.001). Eighty-nine percent of surgeons felt plastics increased operative time (58 ± 37 min), and 34% felt it increased length of hospitalization. Surgeons who routinely utilize plastics were more likely to believe PMC decreases wound complications (P = 0.007). The perceived benefit of plastic surgery varies, highlighting equipoise among pediatric spine surgeons. An evidence-based guideline is needed to optimize utilization of plastics in pediatric spine surgery.

Local contamination is a major cause of early deep wound infections following open posterior lumbosacral fusions. Spine Deform 2023; 11:1209-1221. [PMID: 37147477 DOI: 10.1007/s43390-023-00694-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 04/15/2023] [Indexed: 05/07/2023]
Abstract
PURPOSE Postoperative surgical site infection in patients treated with lumbosacral fusion has usually been thought to be caused by perioperative contamination. With the proximity of these incisions to the perineum, this study sought to determine if contamination by gastrointestinal and/or urogenital flora should be considered as a major cause of this complication. METHODS We conducted a retrospective review of adults treated with open posterior lumbosacral fusions between 2014 and 2021 to identify common factors in deep postoperative infection and the nature of the infecting organisms. Cases of tumor, primary infection and minimally invasive surgery were excluded. RESULTS 489 eligible patients were identified, 20 of which required debridement deep to the fascia (4.1%). Mean age, operative time, estimated blood loss and levels fused were similar between both groups. The infected group had a significantly higher BMI. The mean time from primary procedure to debridement was 40.8 days. Four patients showed no growth, 3 showed Staphylococcus sp. infection (Perioperative Inside-Out) requiring debridement at 63.5 days. Thirteen showed infection with intestinal or urogenital pathogens (Postoperative Outside-In) requiring debridement at 20.0 days. Postoperative Outside-In infections led to debridement 80.3 days earlier than Perioperative Inside-Out infections (p = 0.007). CONCLUSIONS 65% of deep infections in patients undergoing open lumbosacral fusion were due to early contamination by pathogens associated with the gastrointestinal and/or urogenital tracts. These required earlier debridement than Staphylococcus sp. INFECTIONS There should be renewed focus on keeping these pathogens away from the incision during the early stages of wound healing.

Abstract
STUDY DESIGN Retrospective data analysis. OBJECTION The primary objective of this investigation was to analyze if treatment of Postoperative surgical site infections (PSSI) after posterior stabilization of the spine (PS) without radiological signs of screw loosening (RSL) shows a sufficient success rate without implant removal and if there was any difference between early and late PSSI. SUMMARY OF BACKGROUND DATA PSSI after PS are usually treated by implant removal and reinstrumentation if loosening of one of more screws is detected. There is presently no conclusive data that shows the success rate of the treatment of PSSI after PS without implant removal if no RSL are perceived. MATERIALS AND METHODS All patients who were treated for a PSSI after PS without RSL in a single spine center from 12/2009 to 03/2020 were enrolled in a retrospective analysis. Patients were treated by revision surgery with debridement and irrigation and subsequent antibiotic therapy. Implant removal was performed if the initial treatment did not lead to an improvement in wound healing and normalization of laboratory values. Statistical analysis was performed by Statistical Package for the Social Sciences 25. Descriptive data are given as mean and standard error of mean, a χ 2 test was performed. RESULTS Of the 32 enrolled patients, 17 had an early PSSI, 15 a late PSSI. In 71.9% (23/32), the PSSI was treated without implant removal: 12/17 in early PSSI, 11/15 in late PSSI. The difference was not significant ( P >0.05). One patient died, all other patients were discharged from the hospital with no remaining laboratory signs of the infection and with closed soft tissues. CONCLUSIONS In our group of patients, the success rate of irrigation and debridement without implant removal was 71.9%. In the light of this data, performing at least two irrigations and debridement before implant removal seems to be a valid treatment option in PSSI after PS if there are no RSL in early and late PSSI.

Abstract
BACKGROUND Prior "best practice guidelines" (BPG) have identified strategies to reduce the risk of acute deep surgical site infection (SSI), but there still exists large variability in practice. Further, there is still no consensus on which patients are "high risk" for SSI and how SSI should be diagnosed or treated in pediatric spine surgery. We sought to develop an updated, consensus-based BPG informed by available literature and expert opinion on defining high-SSI risk in pediatric spine surgery and on prevention, diagnosis, and treatment of SSI in this high-risk population. MATERIALS AND METHODS After a systematic review of the literature, an expert panel of 21 pediatric spine surgeons was selected from the Harms Study Group based on extensive experience in the field of pediatric spine surgery. Using the Delphi process and iterative survey rounds, the expert panel was surveyed for current practices, presented with the systematic review, given the opportunity to voice opinions through a live discussion session and asked to vote regarding preferences privately. Two survey rounds were conducted electronically, after which a live conference was held to present and discuss results. A final electronic survey was then conducted for final voting. Agreement ≥70% was considered consensus. Items near consensus were revised if feasible to achieve consensus in subsequent surveys. RESULTS Consensus was reached for 17 items for defining high-SSI risk, 17 items for preventing, 6 for diagnosing, and 9 for treating SSI in this high-risk population. After final voting, all 21 experts agreed to the publication and implementation of these items in their practice. CONCLUSIONS We present a set of updated consensus-based BPGs for defining high-risk and preventing, diagnosing, and treating SSI in high-risk pediatric spine surgery. We believe that this BPG can limit variability in practice and decrease the incidence of SSI in pediatric spine surgery. LEVEL OF EVIDENCE Not applicable.

Abstract
BACKGROUND Children with neuromuscular disorders and syndromic scoliosis who require operative treatment for scoliosis are at increased risk for postoperative complications. Complications may include surgical site infection and pulmonary system problems including respiratory failure, gastrointestinal system disorders, and others. The purpose of our study was to determine the effect of a standardized perioperative pathway specifically designed for management of high-risk pediatric patients undergoing surgery for scoliosis. METHODS The High-Risk Protocol (HRP) at our institution is a multidisciplinary process with subspecialty consultations before scoliosis surgery. This was a retrospective chart and radiographic review at a single institution. Inclusion criteria were high-risk subjects, age 8 to 18 years old, who underwent surgery between January, 2009 and April, 2009 with a minimum 2-year follow-up. Diagnoses included neuromuscular scoliosis or Syndromic scoliosis. RESULTS Seventy one subjects were analyzed. The mean age was 13 (±2 SD) years. Follow-up was 63 (±24 SD) months. The study group consisted of 35 subjects who had fully completed the HRP and the control group consisted of 36 subjects who did not. Nine of the 35 (26%) subjects in the HRP had surgery delayed while interventions were performed. Compared with controls, the study group had larger preoperative and postoperative curve magnitudes: 90 versus 73 degrees ( P =0.002) and 35 versus 22 degrees ( P =0.001). Pulmonary disease was more common in the HRP, 60 versus 31% ( P =0.013). The overall incidence of complications in the study group was 29% (10 of 35 subjects) and for controls 28% (10 of 36). There were no differences between groups for types of complications or Clavien-Dindo grades. Three subjects in the study group and 1 in the controls developed surgical site infection. Eleven subjects required unplanned reoperations during the study period. CONCLUSIONS The findings of our study suggest a structured pathway requiring routine evaluations by pediatric subspecialists may not reduce complications for all high-risk pediatric spine patients. Selective use of consultants may be more appropriate. LEVEL OF EVIDENCE Level III, Retrospective Cohort study.

Abstract
PURPOSE To compare the operative implications between adolescent idiopathic scoliosis patients (10-18 years) and young adult idiopathic scoliosis (YAdIS) patients (19-30 years). METHODS This was a retrospective study querying the SRS M&M database for AIS (10-18 years) and YAdIS (19-30 years) cases enrolled between 2009 and 2015. Demographic and surgical parameters (Lenke curve classification, preoperative curve magnitude, approach type, osteotomy type, estimated blood volume (EBV), levels of fusion and ASA scores) were evaluated and compared between groups. RESULTS N = 690: AIS (n = 607) and YAdIS (n = 83). Lenke curve classification distributions in AIS and YAdIS cases were: main thoracic, 293 vs. 34; double thoracic, 42 vs. 5; double major, 159 vs. 15; triple major, 15 vs. 5; thoracolumbar, 85 vs. 17; and lumbar, 5 vs. 6, respectively. Patients with a coronal curve > 90° were significantly greater in YAdIS vs. AIS patients, p = 0.008. Anterior and combined surgery rates were significantly higher in YAdIS, p = 0.028. Two-staged surgeries were significantly higher for YAdIS cohort, p = 0.01. Osteotomy rate was similar between groups, p = 0.42, but proportion of 3-column osteotomies was significantly higher for YAdIS, p < 0.001. ASA (severe systemic disease and some functional limitation) score 3 patients' rate was higher in YAdIS cohort, p = 0.01. EBV was significantly higher in YAdIS, p = 0.01. Average number of levels of fusions between cohorts was not significant, p = 0.87. CONCLUSIONS The operative implications observed with young adult idiopathic scoliosis patients may potentially result in more complex surgical procedures and operative-associated complications than their adolescent counterparts. Further studies are required and should include a larger number of cases, be prospective in nature and verifiable data. LEVEL OF EVIDENCE II.

Abstract
AIM To develop and validate a risk calculator based on preoperative factors to predict the probability of surgical site infection (SSI) in patients with cerebral palsy (CP) undergoing spinal surgery. METHOD This was a multicenter retrospective cohort study of pediatric patients with CP who underwent spinal fusion. In the development stage, preoperative known factors were collected, and a risk calculator was developed by comparing multiple models and choosing the model with the highest discrimination and calibration abilities. This model was then tested with a separate population in the validation stage. RESULTS Among the 255 patients in the development stage, risk of SSI was 11%. A final prediction model included non-ambulatory status (odds ratio [OR] 4.0), diaper dependence (OR 2.5), age younger than 12 years (OR 2.5), major coronal curve magnitude greater than 90° (OR 1.3), behavioral disorder/delay (OR 1.3), and revision surgery (OR 1.3) as risk factors. This model had a predictive ability of 73.4% for SSI, along with excellent calibration ability (p = 0.878). Among the 390 patients in the validation stage, risk of SSI was 8.2%. The discrimination of the model in the validation phase was 0.743 and calibration was p = 0.435, indicating 74.3% predictive ability and no difference between predicted and observed values. INTERPRETATION This study provides a risk calculator to identify the risk of SSI after spine surgery for patients with CP. This will allow us to enhance decision-making and patient care while providing valid hospital comparisons, public reporting mechanisms, and reimbursement determinations.

OBJECTIVE Postoperative surgical site infection (SSI) is associated with greater rates of disability, especially in instrumented spinal surgeries. The management of implant-associated surgical site infections (SSI) is challenging. We analyzed the data from our hospital databases to assess the incidence and characteristics related to postoperative surgical site infection (SSI) after posterior thoracolumbar and lumbar instrumentation. METHODS Patient demographics, infection characteristics, details of treatment, and perioperative factors were reviewed (Jan 2010 to Dec 2020). The Oswestry disability index (ODI), Patient Health Questionnaire-9 (PHQ-9), and Visual Analog Scale (VAS) scores for back and leg pain were analyzed preoperatively and postoperatively until last follow-up. RESULTS Of the 27,881 procedures collected from the databases, 521 were diagnosed with SSI (1.8%), and 191(36.7%) received at least one revision surgery for SSI. Infection rate was significantly higher in patients with lumbar spinal stenosis than those with scoliosis or kyphosis (P<0.01). Methicillin-sensitive Staphylococcus aureus (43.4%) was the most commonly isolated pathogen. The rate of complication secondary to antibiotics treatment was 7.8%, and long-term antibiotic suppression was reported in 15.2% of patients. Instrumentation was retained in 175 patients (91.6%) and all SSIs were controlled without recurrence during the follow-up. CONCLUSION Analysis of 27,881 patients showed an average SSI rate of 1.8%. Patients with deep wound SSI can be successfully treated in most cases with retention of instrumentation. Early diagnosis, positive revision surgery with strict irrigation, thorough debridement, and a long-term course of antibiotics are critical for eradicating infection, retaining implants, decreasing morbidity, and achieving wound healing.

Abstract
Postoperative infections following implant‐related spinal surgery are severe and disastrous complications for both orthopaedic surgeons and patients worldwide. They can cause neurological damage, disability, and death. To better understand the mechanism of these destructive complications and intervene in the process, further research is needed. Therefore, there is an urgent need for efficient, accurate, and easily available animal models to study the pathogenesis of spinal infections and develop new and effective anti‐bacterial methods. In this paper, we provide a general review of the commonly used animal models of postoperative implant‐related spinal infections, describe their advantages and disadvantages, and highlight the significance of correctly choosing the model according to the infection aspect under investigation. These models are valuable tools contributing to the better understanding of postoperative spinal infections and will continue to facilitate the invention of novel preventative and treatment strategies for patients with postoperative spinal infections. However, although they are valid and reproducible in some respects, the current animal models present certain limitations. Future ideal spinal infection animal models may assess the bacterial load of the same animal in real‐time in vivo, and better mimic the human anatomy as well as surgical techniques. Strains other than Staphylococcus aureus account for a large proportion of postoperative spinal infections, and thus, the establishment of models to evaluate other types of microbial infections is expected in the future. Furthermore, novel transgenic models established on advancements in genome editing are also likely to be developed in the future.

Abstract
BACKGROUND Despite tremendous efforts, the incidence of surgical site infection (SSI) following the surgical treatment of pediatric spinal deformity remains a concern. Although previous studies have reported some risk factors for SSI, these studies have been limited by not being able to investigate multiple risk factors at the same time. The aim of the present study was to evaluate a wide range of preoperative and intraoperative factors in predicting SSI and to develop and validate a prediction model that quantifies the risk of SSI for individual pediatric spinal deformity patients. METHODS Pediatric patients with spinal deformity who underwent primary, revision, or definitive spinal fusion at 1 of 7 institutions were included. Candidate predictors were known preoperatively and were not modifiable in most cases; these included 31 patient, 12 surgical, and 4 hospital factors. The Centers for Disease Control and Prevention definition of SSI within 90 days of surgery was utilized. Following multiple imputation and multicollinearity testing, predictor selection was conducted with use of logistic regression to develop multiple models. The data set was randomly split into training and testing sets, and fivefold cross-validation was performed to compare discrimination, calibration, and overfitting of each model and to determine the final model. A risk probability calculator and a mobile device application were developed from the model in order to calculate the probability of SSI in individual patients. RESULTS A total of 3,092 spinal deformity surgeries were included, in which there were 132 cases of SSI (4.3%). The final model achieved adequate discrimination (area under the receiver operating characteristic curve: 0.76), as well as calibration and no overfitting. Predictors included in the model were nonambulatory status, neuromuscular etiology, pelvic instrumentation, procedure time ≥7 hours, American Society of Anesthesiologists grade >2, revision procedure, hospital spine surgical cases <100/year, abnormal hemoglobin level, and overweight or obese body mass index. CONCLUSIONS The risk probability calculator encompassing patient, surgical, and hospital factors developed in the present study predicts the probability of 90-day SSI in pediatric spinal deformity surgery. This validated calculator can be utilized to improve informed consent and shared decision-making and may allow the deployment of additional resources and strategies selectively in high-risk patients. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2022; 31:454-460. [PMID: 34750670 DOI: 10.1007/s00586-021-07050-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Revised: 10/07/2021] [Accepted: 10/28/2021] [Indexed: 12/19/2022]
Abstract
PURPOSE This prospective randomized controlled trial hypothesizes that intra wound vancomycin reduces postoperative infection. METHODS In this RCT study, the patients were randomly divided into two groups of treatment and control. In the treatment group, 1-2 g of intra wound vancomycin was used, and no drug was used for the control group. SSI and the type of microorganism causing postoperative infection were assessed at a three-month follow-up. Factors affecting postoperative infection such as age, sex, site of operation, surgical levels, and risk factors affecting postoperative infection, such as diabetes, blood pressure, ischemic heart disease, smoking, blood transfusion, BMI, neurologic deficit, CSF leakage, UTI, COPD and surgery time were examined in two groups. RESULTS In this study, 375 patients, including 187patients in the treatment group and 188 patients in the control group, were studied. Among the patients, 228 had surgery without instrumentation, and 147 had surgery with instrumentation. There were 12 cases of SSI in the treatment group and 11 in the control group, and there was no statistically significant difference between the two groups. There was no difference between the two groups with and without instrumentation in the evaluation of postoperative infection. In the subgroups with and without instruments, there was no significant difference between treatment and control groups. Due to the microorganism causing the infection, gram-negative bacteria were more common in the treatment group. CONCLUSION Intra-wound vancomycin has no effect on SSI; in addition, it can increase the rate of gram-negative infections.

Abstract
Spinal infections associated with pediatric and adult spinal deformity surgery are associated with postoperative morbidity and mortality along with elevated health-care costs. Prevention requires meticulous technique by the spine surgeon throughout the perioperative period. There is significant variability in the current practices of spinal deformity surgeons with regard to infection prevention, stemming from the lack of reliable evidence available in the literature. There has also been a lack of literature detailing the difference in infection rates and risk factors between pediatric and adult patients undergoing deformity correction surgery. In this narrative review we looked at 60 studies in the adult population and 9 studies in the pediatric population. Most of these studies of surgical site infections (SSI) in spinal deformity surgery have been performed in adult patients, however it is clear that the pediatric neuromuscular patient requires particular attention that we discuss in detail. This narrative review of the literature outlines evidence and compares and contrasts data for preventive strategies and modifiable risk factors to decrease rates of SSI in the pediatric and adult spinal deformity patient populations. In this review we discuss techniques relating to preoperative cleansing protocols, antibiotic administration, gentle soft tissue handling, appropriate closure, drain usage, and intraoperative technique itself to minimize EBL and operative time.

Abstract
OBJECTIVE The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). METHODS A retrospective cohort study was performed using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric database from 2016 to 2018. All pediatric patients with AIS undergoing PSF were identified. Patients were then categorized by whether they had recorded baseline PRF or no-PRF. Patient demographics, comorbidities, intraoperative variables, complications, length of stay, discharge disposition, and readmission rate were assessed. RESULTS A total of 4929 patients were identified, of whom 280 (5.7%) had baseline PRF. Compared with the no-PRF cohort, the PRF cohort had higher rates of complications (PRF, 4.3% vs. no-PRF, 2.2%; P = 0.03) and longer hospital stays (PRF, 4.6 ± 4.3 days vs. no-PRF, 3.8 ± 2.3 days; P < 0.001), yet, discharge disposition was similar between cohorts (P = 0.70). Rates of 30-day unplanned readmission were significantly higher in the PRF cohort (PRF, 6.3% vs. no-PRF, 2.7%; P = 0.009), yet, days to readmission (P = 0.76) and rates of 30-day reoperation (P = 0.16) were similar between cohorts. On multivariate analysis, PRF was found to be a significant independent risk factor for longer hospital stays (risk ratio, 0.74; 95% confidence interval, 0.44-1.04; P < 0.001) but not postoperative complication or 30-day unplanned readmission. CONCLUSIONS Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship of preoperative anemia and outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). METHODS A retrospective cohort study was performed using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric database from 2016 to 2018. All pediatric patients (age 10-18 years) with AIS undergoing PSF were identified. Two cohorts were categorized into anemic and nonanemic cohorts based on age-based and sex-based criteria for anemia. Thirty-day outcomes and readmission rates were evaluated. RESULTS A total of 4929 patients were identified, of whom 592 (12.0%) were found to have preoperative anemia. The anemic cohort had a greater prevalence of comorbidities and longer operative times. Compared with the nonanemic cohort, the anemic cohort experienced significantly higher rates of perioperative bleed/transfusion (nonanemic, 67.4% vs. anemic, 73.5%; P = 0.004) and required a greater total amount of blood transfused (nonanemic, 283.2 ± 265.5 mL vs. anemic, 386.7 ± 342.6 mL; P < 0.001). The anemic cohort experienced significantly longer hospital stays (nonanemic, 3.8 ± 2.2 days vs. anemic, 4.2 ± 3.9 days; P = 0.001), yet discharge disposition (P = 0.58), 30-day complication rates (P = 0.79) and unplanned reoperation rates (P = 0.90) were similar between cohorts. On multivariate analysis, anemia was found to be an independent predictor of perioperative bleed/transfusion (odds ratio, 1.36; 95% confidence interval, 1.12-1.66; P = 0.002) as well as a longer length of hospital stay (relative risk, 0.46; 95% confidence interval, 0.25-0.67; P < 0.001) but was not an independent predictor for postoperative complications (P = 0.85). CONCLUSIONS Our study suggests that preoperative anemia may be a risk factor for a greater perioperative bleed/transfusion event and slightly longer length of stay; however, it was not associated with greater 30-day complication and readmission rates in patients with AIS undergoing PSF.

Abstract
STUDY DESIGN A literature review. OBJECTIVE To summarize the implant removal rate, common bacterial organisms found, time of onset, ratio of superficial to deep infection, and regurgitating the prevalence among all the retrospective and prospective studies on management and characterization of surgical site infections (SSIs). METHODS PubMed was searched for articles published between 2000 and 2018 on the management or characterization of SSIs after spinal surgery. Only prospective and retrospective studies were included. RESULTS A total of 49 articles were found relevant to the objective. These studies highlighted the importance of implant removal to avoid recurrence of SSI. The common organisms detected were methicillin-resistant Staphylococcus aureus, methicillin-resistant Staphylococcus epidermis, Staphylococcus epidermis, Staphylococcus aureus, and Propionibacterium acnes, with prevalence of 1% to 15%. A major proportion of all were deep SSI, with minority reporting on late-onset SSI. CONCLUSION Long-term antibiotics administration, and continuous irrigation and debridement were common suggestion among the authors; however, the key measure undertaken or implied by most authors to avoid risk of recurrence was removal or replacement of implants for late-onset SSI.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To describe pathogens found in SSI during pediatric-instrumented spine surgery, and to assess the relationship between pathogens and the etiology of the spinal deformity. Surgical site infection (SSI) after pediatric spine fusion is a well-known complication with incidence rates between 0.5 and 42%, associated with the patient underlying disorder. Pathogens involved in SSI seem to be related to patient characteristics, such as the etiology of the spinal deformity. GNB (gram-negative bacilli) are more frequent in neuropathic, muscular, and syndromic conditions. High-risk pediatric patients with a spine deformity undergoing instrumented surgery might benefit from receiving perioperative intravenous prophylaxis for GNB. METHODS We conducted a retrospective study at our tertiary-care pediatric hospital from January 2010 to January 2017. We reviewed records of all episodes of SSI that occurred in the first 12 months postoperatively. All patients who underwent instrumented spine surgery were included in this study. RESULTS We assessed 1410 pediatric-instrumented spine surgeries; we identified 68 patients with deep SSIs, overall rate of 4.8%. Mean age at instrumented spine surgery was 12 years and 9 months. Time elapsed between instrumented surgery and debridement surgery was 28.8 days. Cultures were positive in 48 and negative in 20. Of the 48 positive culture results, 41 (72%) were GNB, 12 (21%) gram-positive cocci (GPC), three (5%) gram-positive anaerobic cocci (GPAC), and one (2%) coagulase-negative staphylococci (CoNS). Of the 68 patients with primary SSIs, 46 were considered to have a high risk of infection, which reported GNB in 81%, GPC in 15%, GPAC in 2%, and CoNS in 2%. CONCLUSION Cefazolin prophylaxis covers GPC and CoNS, but GNB with unreliable effectiveness. Gram-negative pathogens are increasingly reported in SSIs in high-risk patients. Adding prophylaxis for GNB in high-risk patients should be taken into account when considering spine surgery. LEVEL OF EVIDENCE IV.

Abstract
Background Surgical outcomes of adolescent idiopathic scoliosis (AIS) patients have been well studied. However, few studies have examined the surgical outcomes of young adult idiopathic scoliosis (YAdIS) patients. This study analyzed and compared the surgical outcomes of young adult (19-30 years) and adolescent (10-18 years) idiopathic scoliosis patients. Methods This is a retrospective, comparative two-center study. Reviewed data of consecutive AIS and YAdIS patients who had undergone posterior spinal deformity surgery (n=56) by two spine surgeons from 2010 to 2014. Inclusion criteria were age between 10 to 30 years and preoperative coronal Cobb angle >40o. We excluded patients with previous correction surgery. Demographic data (age at time of surgery, gender, body mass index (BMI)), surgical data (preoperative diagnosis, number of levels fused, blood loss, duration of surgery, peri- and postoperative complications, duration of surgery, length of stay, revision surgery, and final follow-up) and radiographic data collected, reviewed, and analyzed. The groups were divided as AIS (n=29) and YAdIS (n=27). Results Patients’ gender, BMI, average preoperative main coronal curve (YAdIS 53o vs. AIS 570), and follow-up intervals were not statistically different between groups. Statistically significant for YAdIS patients were more levels fused (10.6 vs. 8.9, p=0.02) and more intraoperative blood loss (872 ml vs. 564 ml, p=0.02) were statistically significant. Not significant between the groups were duration of surgery (p>0.05), perioperative complications (p=0.14), and length of stay (p=0.11). At mean 21 months follow-up, patients in both groups had a significant correction of their main coronal curve (YAdIS 21o vs. 53o, p<0.001, and AIS, 19o vs. 57o, p<0.01). YAdIS had a lower percentage correction of their curves (61% vs. 68%, p=0.03). Three YAdIS (11.1%) and no AIS (0%) patients had additional surgery, p=0.07. YAdIS had more distal fusion levels at L4 or below. Conclusions YAdIS patients had a greater number of levels fused, higher blood losses, and lower major Cobb correction versus AIS patients.

Abstract
In July of 2018, the Second International Consensus Meeting (ICM) on Musculoskeletal Infection convened in Philadelphia, PA was held to discuss issues regarding infection in orthopedic patients and to provide consensus recommendations on these issues to practicing orthopedic surgeons. During this meeting, attending delegates divided into subspecialty groups to discuss topics specifics to their respective fields, which included the spine. At the spine subspecialty group meeting, delegates discussed and voted upon the recommendations for 63 questions regarding the prevention, diagnosis, and treatment of infection in spinal surgery. Of the 63 questions, 9 focused on implants questions in spine surgery, for which this article provides the recommendations, voting results, and rationales.

Abstract
BACKGROUND Considerable variation exists in surgical site infection (SSI) prevention practices for pediatric patients undergoing spinal deformity surgery, but the incidence of SSI has been reported to remain high in the United States. The literature reports various risk factors associated with SSI but findings are inconsistent. The purpose of this systematic review and meta-analysis was to assess the published literature investigating associations between various risk factors and SSI in pediatric patients undergoing spinal surgery. METHODS The systematic review and the meta-analysis were conducted according to Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) guidelines among peer-reviewed journals published in English between January 2000 and April 2019. Studies that involved pediatric patients with spinal deformity undergoing surgical procedures in North America and assessed risk factors for SSI were included. The quality of individual studies was assessed, and weighted risk ratios and mean differences were calculated for each risk factor. RESULTS Of 763 potential articles identified, 13 met inclusion criteria; 7 studies were rated as average and 6, as poor quality based on the quality checklist. The meta-analysis demonstrated that the SSI risk increased by the following factors: 2.53 (95% confidence interval [CI], 1.26 to 5.10) for overweight to obese patients compared with patients with normal weight, 2.84 (95% CI, 1.67 to 4.81) for patients with a neuromuscular etiology compared with non-neuromuscular etiology, 1.69 (95% CI, 1.41 to 2.02) for patients with a gastrostomy tube (G-tube) compared with those without, 3.45 (95% CI, 2.08 to 5.72) for nonambulatory patients compared with ambulators, and 3.39 (95% CI, 2.38 to 4.83) for patients with pelvic instrumentation compared with those without. Patients who developed SSI also had 158.38 mL (95% CI, 46.78 to 269.97 mL) greater estimated blood loss compared with those who did not. CONCLUSIONS Despite the limited quality of the available studies and wide variety of populations and outcome definitions, evidence suggests that overweight to obese status, neuromuscular etiology, use of a G-tube, nonambulatory status, instrumentation to the pelvis, and greater estimated blood loss are risk factors for SSI. The use of a common SSI definition and strong methodology are warranted for future studies. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
BACKGROUND Despite clinical reports of improved pulmonary function and reduced spinal deformity with rib-based distraction surgery in early-onset scoliosis (EOS) patients, infection remains a common complication, reported as high as 32% in some studies. The purpose of this study was to evaluate intrawound vancomycin powder in pediatric patients managed with rib-based distraction for EOS. METHODS This was a single institution retrospective cohort study of EOS patients treated with rib-based distraction. Patients treated with and without intrawound vancomycin were compared. Patients included were younger than 18 years of age, had undergone placement of a rib-based distraction construct, and had a minimum of 6 months' follow-up. For patients in the vancomycin group, 500 mg of vancomycin powder was placed before wound closure. Complications including infection and revision surgery were recorded. P-values and 95% confidence intervals (CIs) were reported for both unadjusted and adjusted complication rates for prevancomycin and postvancomycin powder. All P-values were calculated at a significance level of 0.05. RESULTS In total, 118 patients were included, accounting for 1035 procedures in the nonvancomycin control group and 252 procedures in the vancomycin group. Both groups were similar with regard to age at initial implant, sex, diagnosis, ambulatory status, and bowel/bladder incontinence. There were 55 (5.3%; 95% CI, 4.1-7.6) postoperative infections in the control group and 3 (1.2%; 95% CI, 0.3-3.8) in the vancomycin group (P=0.008, unadjusted). After adjusting for surgery type and transfusions, the vancomycin group still had a significantly lower infection rate (1.4%; 95% CI, 0.3-3.7 vs. 5.5%; 95% CI, 3.04-6.5; P=0.022). We were unable to demonstrate a difference between the control (3.5%, 95% CI, 2.4-5.1) and vancomycin (1.8%, 95% CI, 0.5-5.7) groups for deep infection (P=0.27). CONCLUSIONS Intrawound vancomycin powder significantly reduced the surgical site infection rates following rib-based distraction surgery for EOS. We therefore recommend the use of intrawound vancomycin powder as a standard of care for patients undergoing rib-based distraction surgery. LEVEL OF EVIDENCE Pre-post intervention, retrospective cohort study-therapeutic level III.

Abstract
This study assessed the rate of adverse wound events in individuals with adolescent idiopathic scoliosis who underwent a posterior spinal fusion and sought to determine if obesity was related to the rate of adverse wound events. A retrospective review of patients with adolescent idiopathic scoliosis that underwent posterior spinal fusion between 2001 and 2013 was performed. Preoperative, perioperative, and postoperative data, including wound adverse events, were obtained through medical record review. Using the Center for Disease Control BMI criteria, participants were grouped into overweight/obese (BMI%≥85 percentile) or healthy/underweight (BMI%<85 percentile) groups. Obesity and prolonged hospital stay were independent risk factors for increased risk of wound problems.

Abstract
STUDY DESIGN Retrospective case-control study. OBJECTIVES To identify risk factors for early deep surgical site infections (SSIs; within three months of index procedure) following pediatric spinal deformity surgery. BACKGROUND Deep surgical site infections (SSIs) following pediatric spinal deformity surgery are a source of significant morbidity. We sought to identify independent risk factors for early infection following primary, definitive single-stage pediatric posterior spinal fusion and instrumentation (PSFI). METHODS A total of 616 consecutive patients (2001-2016) from an institutional prospectively maintained Pediatric Orthopaedic Spine database were identified that met inclusion criteria of definitive single-stage PSFI. Early deep SSI was defined as infection within three months of index procedure requiring surgical intervention. A multivariate analysis of demographics, comorbidities, and perioperative factors was performed and independent risk factors were identified. RESULTS Eleven patients (1.6%) developed an early deep SSI. Independent risk factors for SSI identified were nonidiopathic (neuromuscular, syndromic, and congenital) etiologies of scoliosis (adjusted odds ratio [aOR]: 8.384, 95% confidence interval [CI]: 1.784-39.386, p = .007) and amount of intraoperative crystalloids (aOR: 1.547 per additional liter of fluid, 95% CI: 1.057-2.263, p = .025). Mean crystalloid administered in the SSI group was 3.3 ± 1.2 L versus 2.4 ± 1.0 L in the noninfected group (p = .019). On univariate analysis, there was no significant difference in weight of patients between cohorts (p = .869) or surgery time (p = .089). There was also no significant difference in infection rates from redosing of antibiotics intraoperatively after 3 hours of surgery (p = .231). CONCLUSIONS Nonidiopathic scoliosis and amount of intraoperative crystalloids were independently associated with early postoperative SSI. Further investigation into intraoperative fluid management may identify modifiable risk factors for early postoperative SSI in primary pediatric spinal deformity posterior spinal fusion patients. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
STUDY DESIGN Retrospective review of prospectively collected data. OBJECTIVE Analyze the Scoliosis Research Society (SRS) Morbidity & Mortality (M&M) database to assess the incidence and characteristics related to postoperative surgical site infection (SSI) after spinal deformity surgery. SUMMARY OF BACKGROUND DATA Infections involving spinal instrumentation are associated with greater rates of disability. Rates of postoperative SSI after spinal deformity surgery range from 1.9% to 4.4%. Postoperative SSI rates of 4.2% for adult kyphosis, 2.1% for adult spondylolisthesis, and 3.7% for adult scoliosis have been reported. METHODS The SRS M&M database was evaluated to define patient demographics, perioperative factors, and infection characteristics of spinal deformity patients with postoperative spine infections after deformity surgery in 2012. RESULTS Of the 47,755 procedures reported to the SRS in 2012, there were 578 (1.2%) diagnosed SSIs. Infection rates for patients with kyphosis were significantly higher compared with patients with scoliosis (2.4% vs. 1.1%, p < .0001) or spondylolisthesis (2.4% vs. 1.1%, p < .0001). Spinal fusions were performed in 86.3% of patients, 75.1% of which were performed posteriorly. Osteotomies were performed in 30.1% of patients. Deep infections below the fascia accounted for 68.0% of infections. Methicillin-sensitive (41.9%) and methicillin-resistant (17.0%) Staphylococcus aureus were the most commonly isolated pathogens, whereas gram-negative bacteria accounted for 25.4% of cases. Long-term antibiotic suppression was required in 18.9% of patients, and overall complications from antibiotics occurred in 4.5% of patients. Operative treatment was required in 81.8% of SSI cases. CONCLUSION SSIs occur in 1.2% of spine deformity patients, with a rate significantly higher in patients with kyphosis. Approximately 25% of these infections are secondary to gram-negative species. Antibiotic complications occur in 4.5% of patients being treated for SSI. Despite advancements in surgical technique and infection prophylaxis, postoperative SSI remains one of the most common complications in spinal deformity surgery. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE Spinal arthrodesis is routinely performed in the pediatric population. However, there is limited information on the short-term outcomes of pediatric patients who have undergone spine fusion. Thus, the authors conducted a retrospective review of the Pediatric National Surgical Quality Improvement Program (NSQIP) database to determine the short-term mortality, complication, reoperation, and readmission rates of pediatric patients who underwent spinal arthrodesis for all indications. METHODS The Pediatric NSQIP database was queried for all patients who underwent spinal arthrodesis between 2012 and 2014. Patient demographics, comorbidities, body mass index, American Society of Anesthesiologists classification, and operative time were abstracted. Short-term mortality, reoperation, and readmission rates and complications were also noted. Univariate and multivariate analyses were performed to delineate patient risk factors that influence short-term mortality, complications, reoperation, and readmission rates. RESULTS A total of 4420 pediatric patients who underwent spinal fusion were identified. Common indications for surgical intervention included acquired/idiopathic scoliosis or kyphoscoliosis (71.2%) and genetic/syndromic scoliosis (10.7%). The mean patient age was 13.7 ± 2.9 years, and 70% of patients were female. The overall 30-day mortality was 0.14%. Multivariate analysis showed that female sex and pulmonary comorbidities significantly increased the odds of reoperation, with odds ratios of 1.43 and 1.78, respectively. CONCLUSIONS In the NSQIP database for pediatric patients undergoing spinal arthrodesis for all causes, there was a 3.6% unplanned reoperation rate, a 3.96% unplanned readmission rate, and a 9.0% complication rate. This analysis provides data for risk stratification of pediatric patients undergoing spinal arthrodesis, allowing for optimized care.

Abstract
BACKGROUND A multidisciplinary task force, designated Target Zero, has developed protocols for prevention of surgical site infection (SSI) for spine surgery at our institution. The purpose of this study was to evaluate how compliance with an antibiotic bundle impacts infection incidences in pediatric spine surgery. METHODS After institutional review board approval, a consecutive series of 511 patients (517 procedures) who underwent primary spine procedures from 2008 to 2012 were retrospectively reviewed to identify patients who developed SSI. Patients were followed for a minimum of 90 days postoperatively. Compliance data were collected prospectively in 511 consecutive patients and a total of 517 procedures. Three criteria were required for antibiotic bundle compliance: appropriate antibiotics completely administered within 1 hour before incision, antibiotics appropriately redosed intraoperatively for blood loss and time, and antibiotics discontinued within 24 hours postoperatively. A multivariable logistic regression analysis was used to test the association between compliance and the development of an infection. RESULTS Overall antibiotic bundle compliance rate was 85%. After adjusting for risk category, estimated blood loss, and study year, the likelihood of an infection was increased in the noncompliant group compared with the compliant group (adjusted odds ratio: 3.0, 95% CI, 0.96-9.47, P=0.0587). When expressed as the number needed to treat, strict adherence to antibiotic bundle compliance prevented 1 SSI within 90 days of surgery for every 26 patients treated with the antibiotic bundle. Reasons for noncompliance included failure to infuse preoperative antibiotics 1 hour before incision (10.3%), failure to redose antibiotics intraoperatively based on time or blood loss (5.5%), and failure to discontinue antibiotics within 24 hours postoperatively (1.9%). CONCLUSIONS Compliance with a comprehensive antibiotic protocol can lead to meaningful reductions in SSI incidences in pediatric spine surgery. Institutions should focus on improving compliance with prophylactic antibiotic protocols to decrease SSI in pediatric spine surgery. LEVEL OF EVIDENCE Level III-retrospective cohort study.

Abstract
Cell transplant-mediated tissue repair of the damaged spinal cord is being tested in several clinical trials. The current candidates are neural stem cells, stromal cells, and autologous Schwann cells (aSC). Due to their peripheral origin and limited penetration of astrocytic regions, aSC are transplanted intralesionally as compared to neural stem cells that are transplanted into intact spinal cord. Injections into either location can cause iatrogenic injury, and thus technical precision is important in the therapeutic risk-benefit equation. In this chapter, we discuss how we bridged from transplant studies in large animals to human application for two Phase 1 aSC transplant studies, one subacute and one chronic. Preclinical SC transplant studies conducted at the University of Miami in 2009-2012 in rodents, minipigs, and primates supported a successful Investigational New Drug (IND) submission for a Phase 1 trial in subacute complete spinal cord injury (SCI). Our studies optimized the safety and efficiency of intralesional cell delivery for subacute human SCI and led to the development of new simpler techniques for cell delivery into subjects with chronic SCI. Key parameters of delivery methodology include precision localization of the injury site, stereotaxic devices to control needle trajectory, method of entry into the spinal cord, spinal cord motion reduction, the volume and density of the cell suspension, rate of delivery, and control of shear stresses on cells.

Abstract
STUDY DESIGN Therapeutic anti-infective trial in rabbits. OBJECTIVE The purpose of the present study was to assess the efficacy of intrawound tobramycin powder in terms of eradicating a known bacterial contamination in an Escherichia coli-infected rabbit spinal implantation model. SUMMARY OF BACKGROUND DATA Implant-associated surgical site infections (SSIs) remain a dreaded complication of spinal surgery. Currently, >30% of all spine SSIs are secondary to gram-negative bacteria. METHODS Twenty healthy New Zealand white female rabbits underwent simulated partial laminectomies and implantation of a 10-mm titanium wire at L5-L6. All surgical sites were inoculated with 100 μL of tobramycin-sensitive E coli (EC ATCC 25922, 1 × 10 colony-forming units [CFU]/mL). Before closure, tobramycin powder (120 mg) was placed into the wound of 10 rabbits. All rabbits were sacrificed on postoperative day 4. Tissue and wire samples were explanted for bacteriologic analysis. A Fisher exact test was used to assess differences in categorical variables and an independent samples t test was used to assess mean group differences. RESULTS The experimental and control rabbits were similar in weight (mean ± standard deviation, 3.22 ± 0.12 kg and 3.22 ± 0.14 kg, respectively, P = 1.0), sex distribution, and duration of surgery (13.1 ± 2.4 minutes and 11.6 ± 2.1 minutes, P = 0.39). Bacterial cultures of the tissue samples were negative for all 10 tobramycin-treated rabbits and positive for all 10 control rabbits (P < 0.0001). Bacterial growth occurred in 39 of 40 samples from control rabbits, but zero of the 40 samples from the tobramycin group (P < 0.0001). Blood culture samples from all rabbits were negative for bacterial growth. No rabbit had evidence of sepsis or tobramycin toxicity. CONCLUSION In a rabbit spine-infection model, intrawound tobramycin eliminated E coli surgical site contamination. All rabbits without intrawound tobramycin had persistent E coli contamination.

Abstract
BACKGROUND Adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF) experience variations in their hospital care, which may lead to differences in objective and patient-reported outcomes. The purpose of this study was to demonstrate that using plan of care-educating families preoperatively and standardizing some aspects of care-would decrease time to mobility and time to discharge while maintaining pain control and patient satisfaction. METHODS Chart review was conducted in 3 groups-preprotocol (December 2008 to December 2009, n=51), first protocol (December 2, 2009 to July 24, 2013, n=100), and second protocol (July 25, 2013 to June 1, 2014, n=39)-to track pain scores (0 to 10), time to regular diet, Foley catheter removal, epidural catheter removal, mobility, and discharge. Patient satisfaction surveys (0 to 10) were administered before discharge. Statistical analysis was performed using a 1-way analysis of variance test with Tukey post hoc analysis. RESULTS Average pain scores were similar in all groups. Time to sitting was significantly reduced in both first protocol (27.2±9.8 h, P=1×10) and second protocol (28.4±13.6 h, P=3×10) compared with preprotocol (40.2±15.4 h). Time to discharge was significantly lower in second protocol (84.3±27.2 h, P=0.036) compared with first protocol (98.4±27.8 h). Patient satisfaction with care was significantly higher in first protocol (9.1/10, P=2×10) and second protocol (8.6/10, P=5×10) compared with preprotocol (6.5/10). CONCLUSIONS By educating families preoperatively and standardizing portions of postoperative care in PSF for AIS, pain scores were significantly reduced while overall satisfaction remained high. Specifically, by removing the epidural and Foley catheters on postoperative day 2, time to discharge was dramatically decreased by 15 hours. The application of a multidisciplinary, evidence-driven plan of care for AIS patients undergoing PSF improves throughput and has beneficial effects on objective and patient-reported outcomes.

Abstract
STUDY DESIGN A randomized complete block animal spinal implant infection model with internal control. OBJECTIVE The aim of this study was to develop a spinal implant animal infection model to simulate postoperative gram-negative wound infection. SUMMARY OF BACKGROUND DATA Implant-associated surgical site infections (SSIs) remain a dreaded complication of spinal surgery. Currently, over 30% of all spine SSIs are secondary to gram-negative bacteria. Traditional animal models have utilized gram-positive inoculums to simulate postoperative infection, but there exists no model in the literature for gram-negative infection in the setting of spinal instrumentation. METHODS Five New Zealand white female rabbits underwent simulated partial laminectomies and implantation of a 5 mm titanium wire adjacent to the spinous processes of vertebra T4, T9, L1, and L6 to mimic posterior spinal instrumentation. The second site, T9, was used as the sterile internal control sites, while all other sites were challenged with varying inoculums of Escherichia coli (EC American Type Culture Collection 25922): 10, 10, 10, 10, and 10 Colony Forming Units (CFU). The rabbits were sacrificed 4 days postoperatively and bacterial loads were assayed from the implants and surrounding tissue. RESULTS No evidence for infection was observed in any of the sterile control sites. The lowest inoculum of E. coli (10 CFU) did not produce a reliable infection. Inoculation with 10 CFU created a consistent soft tissue infection, but inconsistent infection on implants. Inoculation with 10 CFU was required to consistently produce both soft tissue and implant infection. CONCLUSION Consistent soft tissue and implant infection was produced with inoculation of 10 CFU of E. coli. Gram-negative infections represent greater than 30% of all spinal SSIs, and this animal model can reliably reproduce such infections with spinal instrumentation that can guide future development of anti-infective therapies.

Abstract
BACKGROUND Quality improvement in orthopaedic surgery has received increasing attention; however, there is insufficient information available about the perioperative safety of many common pediatric orthopaedic procedures. This study aimed to characterize the incidence of adverse events in a national pediatric patient sample to understand the risk profiles of common pediatric orthopaedic procedures, and to identify patients and operations that are associated with increased rates of adverse outcomes. METHODS A retrospective cohort study was conducted using the prospectively collected American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Pediatric database. Pediatric patients who underwent 29 different orthopaedic procedures were identified in the 2012 NSQIP Pediatric database. The occurrence of any adverse event, infection, return to the operating room, and readmission within 30 days, were reported for each procedure. Multivariate regression was then used to identify the association of patient and operative characteristics with the occurrence of each adverse outcome. RESULTS A total of 8975 pediatric patients were identified. Supracondylar humerus fracture fixation was the most common procedure performed in this sample (2274 patients or 25.57% of all procedures), followed by posterior spinal fusion (1894 patients or 21.10% of all procedures). Adverse events occurred in 352 patients (3.92% of all patients). Four deaths were noted (0.04% of all patients), which only occurred in patients with nonidiopathic scoliosis undergoing spinal fusion. Infections occurred in 143 patients (1.59%), and 197 patients (2.19%) were readmitted within 30 days. Multiple patient characteristics and procedures were found to be associated with each adverse outcome studied. CONCLUSIONS Spinal fusion, multiaxial external fixation, and fasciotomy were procedures associated with increased rates of adverse outcomes within 30 days. Patients with obesity, ASA class ≥3, and impaired cognitive status also had increased rates of adverse outcomes. The results from this study of a large, national sample of pediatric orthopaedic patients are important for benchmarking and highlight areas for quality improvement.

Abstract
STUDY DESIGN Delphi process with multiple iterative rounds using a nominal group technique. OBJECTIVE The aim of this study was to use expert opinion to achieve consensus on various aspects of postoperative care following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Significant variability exists in postoperative care following PSF for AIS, despite a relatively healthy patient population and continuously improving operative techniques. Current practice appears based either on lesser quality studies or the perpetuation of long-standing protocols. METHODS An expert panel composed of 26 pediatric spine surgeons was selected. Using the Delphi process and iterative rounds using a nominal group technique, participants in this panel were presented with a detailed literature review and asked to voice opinion collectively during three rounds of voting (one electronic and two face-to-face). Agreement >80% was considered consensus. Interventions without consensus were discussed and revised, if feasible. RESULTS Consensus was reached to support 19 best practice guideline (BPG) measures for postoperative care addressing non-ICU admission, perioperative pain control, dietary management, physical therapy, postoperative radiographs, surgical bandage management, and indications for discharge. CONCLUSION We present a consensus-based BPG consisting of 19 recommendations for the postoperative management of patients following PSF for AIS. This can serve to reduce variability in practice in this area, help develop hospital specific protocols, and guide future research. LEVEL OF EVIDENCE 5.

Abstract
Complications following spine fusion for adolescent idiopathic scoliosis can be characterized as either intra-operative or post-operative. The most serious and feared complication is neurologic injury, both in the intra- and post-operative period. Other intra-operative complications include dural tears and ophthalmologic or peripheral nerve deficits, which may be related to positioning. Among the most common post-operative complications are surgical site infection, venous thromboembolism, gastrointestinal complications, and implant-related complications. Significant blood loss requiring transfusion, traditionally considered a known sequelae of spine fusion, is now being recognized as a "complication" in large national databases. Pediatric spine surgeons who care for patients with AIS must be thoroughly familiar with all potential complications and their management.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE To assess the relation between exposure to epidural steroid injection (ESI) before surgery and occurrence of surgical site infection (SSI) for degenerative lumbar spine conditions. SUMMARY OF BACKGROUND DATA The effect of local ESI on the occurrence of SSI is controversial. METHODS Patients who underwent surgery for degenerative lumbar spine conditions at two centers between 2005 and 2015 were identified. Primary outcome measure was SSI within 90 days requiring surgical intervention. RESULTS A total of 5311 patients (age 57 ± 16 years) were analyzed of which 945 (18%) had at least one ESI within 90 days of surgery. One hundred thirty-four (2.5%) patients developed an SSI requiring reoperation. No association of exposure or dose-response relationship was identified between ESI and SSI for any of the time periods (90-, 30-, and 30-90-day). Five (1.7%) of the 290 patients who had at least one ESI within 30 days before surgery had a postoperative infection compared to 129 (2.6%) of the 5021 in the non-ESI group (unadjusted odds ratio: 0.67, 95% CI: 0.27-1.64, P = 0.376). Fifteen (2.0%) of the 761 patients who had at least one ESI within 30 to 90 days before surgery had a postoperative infection, compared to 119 (2.6%) of the 4550 in the non-ESI group (unadjusted odds ratio: 0.75, 95% CI: 0.44-1.29, P = 0.296). CONCLUSION In this retrospective study we investigated whether an ESI and its timing influences the postoperative risk of an SSI. We found no association-exposure or dose-response relationship-between ESI and postoperative infection, even after adjusting for potential confounders, for any of the time periods (90-, 30-, and 30-90-day ESI). In addition, we did find that longer hospital stay, greater EBL, posterior approach, and drain placement were associated with higher infection rates.Level of Evidence: 3.

Abstract
The complex nature of the surgical treatment of adolescent idiopathic scoliosis (AIS) requires a wide variety of health care providers. A well-coordinated, multidisciplinary team approach to the care of these patients is essential for providing high-quality care. This review offers an up-to-date overview of the numerous interventions and safety measures for improving outcomes after AIS surgery throughout the perioperative phases of care. Reducing the risk of potentially devastating and costly complications after AIS surgery is the responsibility of every single member of the health care team. Specifically, this review will focus on the perioperative measures for preventing surgical site infections, reducing the risk of neurologic injury, minimizing surgical blood loss, and preventing postoperative complications. Also, the review will highlight the postoperative protocols that emphasize early mobilization and accelerated discharge.

Abstract
Surgical site infection (SSI) after spinal deformity surgery is a complication in the pediatric population resulting in high morbidity and cost. Despite modern surgical techniques and preventative strategies, the incidence remains substantial, especially in the neuromuscular population. This review focuses on recent advancements in identification of risk factors, prevention, diagnosis, and treatment strategies for acute and delayed pediatric spine infections. It reviews recent literature, including the best practice guidelines for infection prevention in high-risk patients. Targets of additional research are highlighted to assess efficacy of current practices to further reduce risk of SSI in pediatric patients with spinal deformity.

Abstract
STUDY DESIGN A retrospective cohort study. OBJECTIVE The aim of this study was to determine the incidence and risk factors for short-term morbidity following posterior spinal fusion (PSF) for neuromuscular scoliosis (NMS). SUMMARY OF BACKGROUND DATA NMS is a challenging spinal deformity for which PSF is often recommended. There is a lack of information on risk factors for short-term adverse outcomes after PSF for NMS. METHODS Patients who underwent PSF for NMS during 2012 and 2013 were identified from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) Pediatric database. Patient characteristics were tested for association with adverse events, infectious complications, extended length of stay (LOS), and readmission using multivariate regression. RESULTS Of the 940 NMS patients identified, 133 (14.1%) had an adverse event and 99 (10.5%) had a severe adverse event. American Society of Anesthesiologists (ASA) classification ≥3 was found to be the only independent risk factor for any adverse event (relative risk [RR] 2.2, P = 0.012) and severe adverse events (RR 2.5, P = 0.008). Infectious complications were associated with body mass index (BMI)-for-age ≥95th percentile (RR 2.8, P = 0.005), ASA classification ≥3 (RR 5.9, P = 0.003), and instrumentation to the pelvis (RR 1.8, P = 0.039).A total of 254 patients (27%) spent longer than a week in the hospital postoperatively, and ASA classification ≥3 (RR 2.3, P < 0.001), preoperative seizure disorder (RR 1.4, P = 0.002), previous cardiac surgery (RR 1.6, P = 0.004), operative time ≥470 minutes (RR 1.8, P < 0.001), and ≥13 levels instrumented (RR 1.9, P = 0.001) were associated with extended LOS.Seventy-six patients (8.1%) were readmitted, and BMI-for-age ≥95th percentile (RR 1.8, P = 0.033) was the only risk factor found for readmission. CONCLUSION The identified factors associated with poor short-term outcomes after PSF for NMS can be used as benchmark data, be useful for optimizing patient care, and can inform future studies in these patients.
